摘要

The glass forming ability of the (Nd,Fe,B)₉₆Nb₄ system has been studied and the best glass former is Fe_65.28B₂₄Nd_6.72Nb₄, with a critical diameter of 4 mm. After subsequent crystallization, the Fe_64.32B_22.08Nd_9.6Nb₄ alloy with a uniformly distributed Nd₂Fe₁₄B phase shows typical characteristics of a hard magnet with a coercivity of 1100 kA m^-1 and an energy product of 33 kJ m^-3. The combination of hard magnetic properties and the large critical sample size may make Fe-Nd-B-Nb a commercially viable candidate for industrial applications.
